What is an LED?

LED stands for “light emitting diode” and it is a semiconductor device that converts an electrical current to visible light. It is a self-emitting light source. Because of its relative power efficiency, solid-state design, and long life-span it is a popular building material for a number of product categories:

LED architectural lighting, replacing incandescent or fluorescent bulbs in light fixtures both indoor and outdoor. These LEDs are structured to emit white light.

LED backlights used in LCD (liquid crystal displays) and video walls as a light source, replacing cold cathode fluorescent lights (CCFL) in flat panel displays and monitors. In consumer products, these LED-backlit LCD displays are called “LED TV”. These LED backlights can be structured to emit white light or can also be controlled to create wider color gamut displays.

LED projection engines replacing other light-emitting bulb materials to produce the light that shines against mirrors or through lenses to create front and rear-projection (RPC) solutions.
